The National Weather Service is upgrading a piece of equipment that helps forecast the weather for the Regional Radio listening area. Work is being done to upgrade the Doppler radar in Lincoln, that helps meteorologists get a better look at what’s going on inside the storms that blow through Central Illinois.

Matt Barnes is a meteorologist with the National Weather Service, and says the work has been going on since last week.

Central Illinois is currently under a heatwave, bringing the hottest temperatures seen so far this year. Barnes explained what’s bringing the hot temperatures to the region.

Barnes appeared as a guest on the Newstalk WTIM Morning Show.
